found some lockers on line for my 9inch most are 31 spline but for street rods will they fit my 9inch out of a 79 f150?arent all 31 spline big bearing?thanks for the help.
yes they will fit...no all 31 spline are not big bearing, BUT, the big bearing is not refering to the carrier bearings, it refers the the bearings at the end of the axle housing...ALL the carriers for the 9" are the same, there is no carrier break or anything with the 9"
